u-blox Pens A Deal For Cutting Edge Navigation Technology

u-blox, a supplier of positioning and wireless communication technologies, has signed a deal with UK based technology company, Focal Point Positioning, to integrate technology that will improve the accuracy and reliability of GNSS devices.

The technology enhances positioning performance and security and will be suitable for applications such as smart cities, location-secure IoT and health and fitness wearables.

Focal Point's patented Supercorrelation technology solves a critical weakness in GNSS that's caused by multipath interference. Multipath interference occurs when satellite signals bounce off buildings and landmarks, causing GNSS receivers to provide degraded positioning outputs. The result for users is that the blue dot on their phone or device may be in the wrong place, moving in the wrong direction, or may have a large error ellipse. For autonomous vehicles it could lead to positioning errors that place the vehicle in the wrong lane or worse.

The Supercorrelation technology uses software to detect and reject reflected signals, resulting in an improvement in the performance of GNSS devices without the need for additional hardware or applications. Supercorrelation also helps with the detection and rejection of GNSS spoofing signals - an increasing concern for autonomous vehicles, ships, and aviation.

Commenting Focal Point Positioning CEO Ramsey Faragher said, “We are tremendously excited to be working alongside a market leader such as u-blox, our mission is to improve every positioning system on the planet and we have taken a giant step forward in that vision with this deal. Positioning systems are so critical to our world, and we look forward to seeing the next generation of products and services that will be enabled by this higher level of accuracy, reliability and security”.

u-blox CEO Thomas Seiler added, “The addition of Supercorrelation technology into our latest GNSS platforms is part of our continuing focus on low power consumption, higher accuracy and security for automotive, industrial, and wearable GNSS applications”
